For Trade: Marantz ST6000 Tuner, Like new (opened once) for Preamp or Trades

Not sure if there's FM interest here but I got a black Marantz ST6000. I bought a pair of tuners (keeping st7001) from a gentleman, he opened this once or twice. Comes with Box, manual, remote. I thought I'd have use for another tuner but I don't. The hard to get station I wanted, plays beautifully...

Looking for a preamp with volume control, custom, homemade, I don't care. I do request that it's complete and finished and hopefully sounds pretty nice.
